Having bought one of these recently I can really recommend it to anyone looking for a backup power supply for their Nexus 4 phone (or pretty much any device that has a similar power requirement).
Unfortunately modern smart phones universally offer fairly poor battery life with daily charging being the norm. Hopefully this is something that will improve in time but until then an external battery is an essential back up when on the move. I bought the Astro3E and have found it invaluable, easily the best accessory I have bought for my phone.
The Anker Astro3E is an external power pack that you can use to charge your mobile devices on the move. It has two standard USB ports that you can simply plug your regular charging cable into and away you go.

The idea is that whilst out and about you can use this as an emergency power supply. Now of course many of you will be thinking that the Nexus 4 battery life is good enough to last a day and that this kind of backup isn’t really needed.
To some extent I agree, this is not a product that I use on a daily basis. I have a charger at work and whilst I am at my desk my Nexus 4 is normally plugged in. I do use the phone a lot but never have a problem lasting a day, and often longer if it is sitting in my pocket unused.
These external battery packs really come into their own when on holiday or travelling on a longer journey. You’ll be very popular on a weekend festival trip if you have a large capacity battery fully charged.
So why do I recommend the Anker power pack? Because when those infrequent occasions where I wish I had more power do crop up, it’s normally under circumstances where I really really need it!
Perhaps you’re at a festival for a couple of days and need to stay in touch with friends, or you get stuck in a traffic jam from hell and need something to distract the kids. Whatever it is, it’s normally a situation where you are sitting there thinking “if only I had more power”.
The Astro3E can provide around 40hr of additional phone time. More than enough to get you out of a tight spot.
